Letters Patent N 96,003, dated October 19, 1869.

IMPROVED CHALK FOR USE AT BILLIARD-TABLES.

The Schedule referred to in these Letter. Patent and making part of the lame.

To all whom it may concern:

Be it known that we, THOMAS HARRISON, of Detroit, in the county of Wayne, and WILLIAM HOLL- MAN and WILLIAM CHART, of Three Rivers, in the county of St. Joseph, and State of Michigan, have invented ailew and valuable Improvement in'Ghalk for Billiard-Cues; and we do hereby declare that the following is a full, clear, and exact description of the same.

Our invention relates to preparations intended for use upon the leather points of billiard-cues, to make them adhesive to the balls; and

It. consists mainly in a novel admixture and compound of substances that serve not only the ordinary uses of chalk for the'purpose named, but also the purpose of preserving the color of the cloth of the billiard-table, and of securing greater neatness in the appearance of such tables than is possible by the use of chalk alone.

For the purposes above mentioned, we make a compound of common chalk and chrome-green, Brunswickgreen, or any other suitable green pigment, together with glue, gelatine, gum, or other adhesive material, mixed in such proportions as to give it the color of the table-cloth, and suflicient adhesive power.

The compoundis then moulded into balls of the size desirable for use.

' We prefer, to all others, andrecommend the following formula, to wit:

Take five parts of chrome-green and three parts of chalk, andafter thorough pulverization, mix well together, and form them into a paste with water and glue, at the rate of one hundred and twenty grains of glue to one-half pint of water.

The paste thus formed is then moulded, in brass moulds, of the size the operator desires.

It will readily be perceived that the preparation above described, being of the same color as the table-cloth, can'never discolor it, as is often done with 'white chalk, and that neatness as well as economy two witnesses.
